Profile: Dhanam Electricals is a distributor of a wide range of automation products. Our product range includes automatic controllers, industrial pressure transducers, melt pressure transducers, absolute pressure transducers and relays. We also offer electronic sensors, proximity sensors, inductive proximity sensors, capacitive proximity sensors and safety light curtain. Proximity sensors are used to detect the presence of nearby objects without any physical contact. It emits an electromagnetic or electrostatic field, or a beam of electromagnetic radiation (infrared, for instance) and looks for changes in the field or return signal. Target is the term used to define the object being sensed by the sensors. Different targets demand different sensors so a inductive proximity sensors, capacitive proximity sensor and photoelectric sensor is suitable for sensing a plastic target and an inductive proximity sensor senses metal targets. We offer solid state relay, which is available in different forms such as photo-coupled SSR, transformer-coupled SSR and hybrid SSR. These solid state relays are electronic devices that contain no moving part. Our photo-coupled SSR is controlled by a low voltage signal, which is isolated optically from the load.
